Oh, it's just that when Adam, Peter, and I compared the M3s, M50s and M80s, we heard the same thing--a reduced high end (in comparison). I promptly forgot about that comparison, but now I'm just wondering if something is wrong.

Maybe during that test the binding straps were a little loose? That would give lowered high frequencies. One bad driver?

During Mojo and I's testing of the M60,M22 and M80, the M22s were the most bright followed by the M80 and then M60. When we had Robb's M3s, we found them to be more like the M60s, still less bright/forward than the M80's and even lesser than the M22's.

I am still thinking that the AB's are probably like the M22's and M2's(I have never listened to these yet) and should sound more forward/bright than the M80s.

Since you stated the M3's/M50s being brighter than the M80s, which most around here don't agree with, certainly sounds like you might have something wrong.....er, with the speakers or receiver that is.

Nope, the tests were about a year apart, and I've attached and detached the cables a couple of times since. Also, my cabling system pretty much avoids this altogether. It doesn't seem to be a bad tweeter; I've checked this a few times.

Hope it's not the receiver... that's out of warranty, and I can't swing a new one right now.

Do the M80s sound good? If so, I think you are looking for an inexisting problem. If there was an actual problem, I'm pretty sure you would know with confidence there was one. Room acoustic can also play tricks at times.

Try test tones with a SPL meter if you want to make absolutely certain.
